GUI rust tokio egui
Overview

Example using tokio with egui

This example uses reqwest to send an HTTP request to httpbin. The parsed response contains an increment value (as provided in the request) that is finally sent to the main GUI thread.

Disclaimer

This is the worst possible way to increment a counter, but it demonstrates awaiting async tasks without blocking the main GUI thread. It is also a very poor use of tokio. Awaiting the future in a thread with pollster is both easier and just as efficient. But if you actually need tokio, this is how to use it with egui.

    Websocket implementation

    Hey, any idea how you would implement this for a websocket connection? I'd like to pass some messages from the websocket connection in a separate thread to the the GUI in the main thread, so it can plot some values from the websocket connection. How would I go about doing this?

    Also, in the send_req function, where does the spawned thread live? I'm having some trouble understanding that, since i thought u'd have to spawn the thread in the main.rs main function
